Posts: 93 virginia beach, VA | I have a Supercat 19 that i have rebuilt over the last few years... i've decided i want to add a boom so i can depower the boat and get better sail shape in different wind conditions...... as of now i have a mast rotation arm at the base of the mast going to some blocks on the front beam and out to cam cleats.... i really don't like this set up and would rather get some help designing a boom... i have a windsurfer mast i am going to use and a boom connector plate from a prindle 19 to rivet to the mast.... just not sure if i should use a harken track to control the sail outhaul... any input would be great.....

Unregistered | Does your boomless setup use a track as an outhaul? Are you modifying your mainsail to go with a boom? | | | Re: boom ideas...

Posts: 93 virginia beach, VA | no.. my main sail just uses stainless steel plates sandwiched on either side f the sail with multi. holes for locating the mainsheet.. but i am planning on having a square top made at a later date....

Unregistered | Gotcha. I see how that is limiting. I sail with a SC19 that is boomless. He has a track on the mainsail that acts as an outhaul and with the mast rotator controls they are able to shape the sail very well... but the outhaul track is key. I PERSONALLY would do that and not install a boom. Unless you are racing... i find boomless a great feature.
I also sail with several GCats that are boomless,and simply have a clew plate... they are very fast but Hans (the Gcat designer) does use a boom sometimes on his GCat... | | | Re: boom ideas...

Posts: 217 | I recommend just installing a clew track on your mainsail, instead of adding al the weight of a boom. I've done this on my 5.7. Adding an over-rotator at the mast base, to control mast position downwind is also very helpful when racing boomless rigs
